For example, $1.5 chinese "switzerland" tweezers were way better than 5 times as expensive bought here... 2012-03-05 22:00 DocScrutinizer: oh. yes. a battery. that answers the question. 2012-03-05 22:00 sometimes for me that pretty much actually does 2012-03-05 22:01 I also dislike batteries 2012-03-05 22:01 we want supercapacitors. 2012-03-05 22:03 lemme do the math: battery: 2$, selfdischarge EOL: after 2 years the latest, number of usage during that period (YMMV): max 10 times avg. 2012-03-05 22:03 so one usage would cost me 20ct 2012-03-05 22:03 not to mention the ecological impact 2012-03-05 22:04 plus inconvenience of flat bat when I *really* need it 2012-03-05 22:04 viric: do you like RoHS too? 2012-03-05 22:04 whitequark: I don't know details of it 2012-03-05 22:04 whitequark: I've only seen marketing 2012-03-05 22:04 ... or maybe think that there is "damage to ozone layer" which is "harmful to the planet"? 2012-03-05 22:06 I think a digital caliper is more polluting than a mechanical caliper 2012-03-05 22:06 for a very little win 2012-03-05 22:06 sigh 2012-03-05 22:06 on the topic of supercaps: we already have two kinds 2012-03-05 22:07 1) ionistors, but they kinda self-discharge in a few days 2012-03-05 22:07 2) rechargeable lithium batteries. have (almost?) the same look as the common coin-cell ones, but can be recharged with a small constant current; used in RTCs 2012-03-05 22:07 through I don't know where one can buy the 2) 2012-03-05 22:08 and afaik they can't be recharged in the "cellphone" mode, that is, go from 0% to 100% in a few hours 2012-03-05 22:09 DocScrutinizer: for me, the problem with these batteries is that you'll have a hard time finding $RANDOM pcs of LR$RANDOM when you least want to deal with it 2012-03-05 22:16 DocScrutinizer: i think my battery-powered one has been up for more than 2 years by now. still works great. probably hundreds of measurements in that time. i use it almost daily. ymmv indeed :) 2012-03-05 22:18 DocScrutinizer: i don't quite like the short (~ 1 yr) battery life of my micrometer, though. but then, that one is kinda hard to read without electronics.
